The Arduino platform has become quite popular with people just starting out with electronics. It is an open-source hardware design, based on microcontroller board designs and provide sets of digital and analog I/O pins that can be interfaced to various expansion boards ("shields") and other circuits. The boards feature serial communications interfaces, including USB on some models, for loading pro...
This schematic uses two LDRs (Light dependent resistor) to sense the light and a servo motor to automatically rotate the solar panel in the direction of the sun light. The Arduino code is available on [Arduino Solar Tracker using LDR and Servo Motor]
**Motherboard for LittleBOT.**
LittleBot is a small robot equipped with a control card with an Arduino Nano. The chassis is made of aluminum and is moved by two small motor-driven motors made entirely of metal that move a pair of tracks.
The robot has some sensors that allow it to detect some parameters including brightness and temperature. A front-mounted sensor powered by a servomotor allows t...
This project is an open source Arduino Nano robotics project. It uses an L293D as a motor controller, and has inputs and outputs for an external 7-12V battery pack, as well as output pins for the motors.
There are two porto-pin areas available as separate 4x2 headers for use with extra sensors, radio antennas etc.
Smoothing capacitors can be added to both the power supply-input as well as...
